Submersible dirty water/dewatering pump UNILIFT KP 250-A1 230V, 0.48kW, 5m cable with SCHUCO plug 012H1600

Submersible dirty water pump – reliable drainage

This powerful Grundfos Unilift KP 250-A1 submersible pump is designed for reliable pumping of dirty water, grey water and liquids containing impurities. It is suitable for both domestic and professional applications, offering versatility and durability. Ideal for removing water from flooded basements, excavations, tanks and other places requiring quick and effective drainage.

Design and application

The Unilift KP 250-A1 pump is a vertical, single-stage unit made of stainless steel. Its compact design allows for easy installation and portability. Equipped with a suction strainer to prevent larger impurities from entering the pump, which increases its lifespan and minimizes the risk of failure. The semi-open impeller with a diameter of 10 mm allows pumping of liquids containing solid particles. The integrated float switch automatically starts and stops the pump depending on the water level, providing convenience and energy saving. The motor housing made of stainless steel 316 (1.4401) guarantees corrosion resistance even in harsh environmental conditions.

Performance and technical parameters

The pump achieves a maximum capacity of 11.2 m³/h and a maximum head of 7.5 m, making it an effective tool in many drainage applications. The 0.48 kW (P1) motor operates at a voltage of 220-230 V and a frequency of 50 Hz. The IP68 protection class ensures complete hermeticity and the possibility of immersing the pump to a depth of 2 meters. Insulation class F guarantees safe and reliable motor operation. The length of the power cable is 5 meters, and the cable termination is a SCHUCO plug – ready to work immediately after connecting to the power source. Thermal protection protects the motor from overheating during intensive operation. The nominal operating mode S3 means that the pump is designed for intermittent operation with cyclic load.
